4 Claims.

This invention relates to improved load supporting spring structures and in particular relates to improved day bed structures.

The principal object of the present invention is to provide a day bed structure having relatively movable frame members in which spring elements are provided on each of the frame members which form independent soft spring surfaces when the frame elements are in their extended position and which combine to provide a single load supporting surface of combined strength when the frame members are in their closed position.

Further objects of the present invention are to provide an improved day bed structure having a pair of frame members so mounted relative to each other that they may be moved from a closed position to an extended position and when in the extended position are in interlocking engagement with each other; to provide a day bed structure in which the movable frame members are so constructed and arranged relative to each other that one of the frame members forms part of the supporting means for the other frame member; and to provide a day bed structure which is simple and economical in construction.

Other objects of the invention will become apparent from the following specification, the drawing relating thereto and from the claims hereinafter set forth.

In the drawing in which like numerals are used to designate like parts in the several views throughout:

Figure 1 is a top plan view of a day bed frame structure embodying features of the present invention;

Fig. 2 is a fragmentary cross-sectional view taken substantially along the line 2-2 of Fig. 1;

Fig. 3 is a fragmentary cross-sectional view taken substantially along the line 3-3 of Fig. 1;

Fig. 4 is a broken, partial cross-sectional View taken substantially along the line 3-4 of Fig. 1; and

Fig. 5 is a fragmentary, cross-sectional View taken substantially along the line 5--5 of Fig. 1.

Referring to the drawing, for the purpose of illustration a day bed is shown comprising an outer frame member l9 preferably made of metal angle members l2, l3, l4 and i5 defining the frame edges. The frame member 19 is supported preferably adjacent its corners by upstanding angle members 16 having casters l8 secured to the bottom thereof in the usual way. Transversely extending bowed spring elements 20 span the frame member [0 and are suitably secured to the front and rear edges l2 and I4, respectively, of the outer frame member Ill.

The spring surface formed by the elements 20 is disposed in an arcuate plane; and the elements 20 are preferably of the type disclosed in the Kaden Patent No. 2,002,399, issued May 21, 1935, and under which the applicants assignee is an exclusive licensee. Spring elements of this type are formed by sinuously bending a suitable spring wire and curving the sinuous wire longitudinally of its length to provide a set therein on an arc materially less than the arc it assumes when employed with the frame. The ends of the elements are spread and secured in arc position to have the unsecured portion between the ends provided with a. tension to resist downward displacement.

In order to reinforce the frame member l0 and provide a support for the other frame member, in a manner to be hereinafter described, elongated downwardly opening channel members 22 are bent upwardly adjacent their ends and are secured to the front and rear edge members 12 and I4 of the frame member II] by spot welding or the like.

An inner frame member 24, complementary in shape to the frame member In and of substantially the same width but of less length, is provided, the frame member 24 being defined by the angle elements 26, 21, 28 and 29. In order to movably mount the inner frame member 24 relative to the outer spring member III in telescopic relation to each other, openings 30 are provided in the downwardly extending flange of the front edge element l2 adjacent the ends thereof. The openings 30 are adapted to slidably receive therethrough end elements 21 and 29 of the outer frame member 24.

The frame member 24 is mounted adjacent its front edge 26 by means of upright leg members 32, similar to the leg members I6, adjacent the corners of the front edge element 26; and the downwardly extending flange or the rear edge element 28 rests upon and is slidably supported by the transversely extending members 22. Transversely extending members 34, similar to the members 22, are preferably secured to the front and rear edge members 26 and 28 of the inner frame member 24 in longitudinally spaced relation in order to reinforce the inner frame member.

To provide the load supporting spring surface for the inner frame member 24, transversely extending spring elements 36 span the frame member 24 and are suitably secured to the front and rear edges 26 and 28, respectively, of the inner frame member. The spring elements 36 are similar in structure to the spring elements 20 described above.

Referring to Fig. 1, the spring elements 20 and 36 are preferably alternately arranged on their respective frames so that when the frame members l and 24 are extended to their open position as indicated by the broken lines in Fig. 1, the elements 20 form an independent soft spring supporting surface for the frame l0 and the elements 36 form an independent soft spring supporting surface for the frame 24. It is evident from the above that when theframe elements are in their extended position providing a double bed;

that the spring elements on the respective frames provide soft comfortable spring supporting surfaces of sufficient strength to support persons in reclined positions on the respective spring surfaces. Further .when the frame members are moved to their closed positions, as indicated by the full lines in the drawing, the spring elements on their respective frames combine to form a single load supporting surface of combined strength. Thus, when the frame elements are in their closed positions, the load supporting surface provided by the combined spring elements is of sufiicientstrength to provide a soft spring supporting surface for a number of persons for use as a divan in the usual way.

Further, when the frame members are in their extended position, the upturned portions of the elongated members -22 adjacent the front edge engage the downwardly directed flange of the rear edge element 28 of the inner frame member; and the upwardly directed portions of the elements 34 engage the downwardly directed flange of the front edge element I2 of the outer frame member so that the frame members are in interlocking engagement. F

Formal changes may be made in the specific embodiment of the invention described without departing from the spirit and substance of the broad invention, the scope of which is commensurate with the appended claims.

What I claim is:

1. A day bed comprising separable frame elements, the main frame element having legs, the slidable frame element having legs only on the forward side thereof, cross braces interconnecting the longitudinal sides of each of said frames, the rear longitudinal side of the slidable frame resting upon the cross brace of the main frame While the front side of the main frame rests upon the cross braces of the slidable frame, and spring elements interconnecting the longitudinal sides of each of said units.

2. A day bed comprising an outer frame member, an inner frame member, said frame memmembers bers having bracing members with upwardly extending end portions between which an element of the other is disposed, and transversely bowed spring elements secured to each of said frame at spaced intervals longitudinally thereof "for providing a resilient surface and for confining the elements between said ends of the bracing members.

3. A day bed comprising two supporting frame elements movably mounted relative to each other to extended and closed positions, bowed spring elements secured across each of said frame elements respectively, and bowed bracing members having the ends extended upwardly and secured to said frame elements with a portion of one of the frame elements confined between the ends of the bracing elements of the other frame element for retaining said frame element confined relative to the other.

4. A day bed comprising a first frame member having bowed zig-zag spring members forming a spring surface, a second frame member having similar bowed zig-zag spring members connected thereto forming a spring surface, said frame members being movably mounted relative to each other for movement to telescoped and extended positions, and U-shaped bracing elements having upwardlyextending arms secured to the frame members with a portion of one frame member confined between the arms of the bracing members of the other frame member to'retain the one frame member relative to the other.
